Magic Containers are items from Zelda II: The Adventure of Link. Each container adds one "block" to Link's Magic Meter. Each block represents 16 magic points. Link begins the game with four blocks, totaling 64 magic points; over the course of the game he can find an additional four Magic Containers, for a total of eight blocks (and therefore, 128 magic points). Link must locate all four magic containers to learn the Thunder Spell, which is required to complete the game.
